Question and Answers

Q:

GU2400XTPT6 Dishwasher doesn't rinse after wash cycle.

A:

Thank you for your question and I understand your concern.

Based on your symptom and details, I must assume the drain pump is jammed or faulty. You will need to remove the front lower access panels and check to see if the drain pump is jammed. If the drain pump hums instead of running and pumping water out; it's likely getting the proper voltage supply (120). The drain pump can be easily remove and check for any blockages.

NOTE: Disconnect the dishwasher from the power supply before removing the lower access panels.

I added an image below with the procedure of removing the drain pump.

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.

Geoffrey: So you say it will fill and wash and then hums? After the washer cycle is completed, the next step is to drain the water out. If it drains water and washes then I guess I do not fully understand what is going on. You say it will drain, but how to get it to drain if it just hums after the wash cycle is completed? If will not drain in the cycles but will if you press Cancel/Drain, then I would have to suspect a control board issue. If you would add additional details I may have better understanding of the problem. When it hums, let it hum a minute or and then open the door and see if drained.

Geoffrey; Okay now I understand; it's not always filling with water. Check the float dome in the front corner of the tub. If for some reason the float is rising and sticking in the up position, the float switch will open and break the electrical circuit to the water inlet valve. Slowly raise and let the float lower and make sure it comes all the way down and trip the micro switch up under the tub. You may need to leave the water inlet valve connected and place the voltage meter leads across the two wires terminals connected to the water inlet valve and sit there and monitor the voltage to the water inlet valve. It should always refill with water after a few seconds after it competes the drain cycles. Note: I do not recommend monitoring the voltage to the water inlet valve unless you have experience and feel safe and confident in doing so; otherwise I recommend calling a service technician to diagnose and repair your dishwasher.

A:

Geoffrey: The door latch and door switch would not relate to the dishwasher not re-filling after the first wash and drain cycle has completed. It's beginning to sound like a control board issue if the control is not supplying the 120 volts to the water inlet valve assembly after the initial fill and wash cycle. I would have to assume a component on the control could be failing after the component gets hot. I added an image below showing how to run a diagnostic test to see if fills during the test. Again, it sounds like it will need a new control board if the control is not providing voltage to the water inlet valve when it should be filling. The part number of the control is 8564547.

Geoffrey: It's odd that it will fill the first time and not the second time? I hope the technician can properly diagnose and repair the issue for you.

A:

Geoffrey: You will need to remove the front lower access panel to access the water inlet valve. Turn the hot water supply off to the dishwasher. Squeeze the hose clamp securing the rubber hose to the water inlet valve and slide it up the hose. Pull the rubber hose off. Pull the wire harness connector from the water inlet valve. Loosen and disconnect the water supply fitting connecting to the water inlet valve. Remove the screw securing the water inlet valve to the frame and remove the valve. Remove the brass fitting from the old water inlet valve and wrap some Teflon tape around the male threads and re-install the brass fitting into the new water inlet valve. Reverse the procedure to install the new water inlet valve. We do not have a video showing how to remove and replace the water inlet valve. You should not have any problems in removing and replacing the water inlet valve.

Q:

Why Does My Undercounter Dishwasher Leave Suds At The Bottom Of THe Drain Holes

A:

Residual suds left on the bottom of the tub after a completed wash cycle could be caused by:

  • Using too much detergent for the type of water conditions (if you have a water softener use less detergent)
  • Wrong kind of detergent (I recommend Cascade powder)
  • Rinse agent leaking into the wash/rinse water (look for a trail of rinse agent under the dispenser assembly)
  • Rinse agent set to dispense too much rinse agent
  • Value branded detergent (buy name brands)
  • Dishwasher not filling with enough water
  • Pre-rinsing dishes
  • Using one of those rinse aide baskets hung from the rack.
  • Soft water
